You only use flash at it's best when you use the power of animations. The component called geoMovieclip makes this easy.
This example describes you how easy you can add movieclips towards a map.
Step 1: Open a new document and follow example 1.
Step 2: Make a new movie clip. (Insert New Symbol). Give this movie clip a name (example 'fire_mc'). Make sure you export the movieclip by checking "export for Actionscript" (see picture). Add anything you like inside this movieclip. A simple circle might do for now. Be aware that you can do anything you like in such movie clip.
Step 3: Drag a geoMovieclip-component to the stage and open the properties. The geoMovieclip component allows you several options but here we only will focus on the "target_intance_name", "fieldname" and "fieldmovieclips".
The target_instance_name is the instance of the Mapviewer-components. In this example it is called 'm'.
The fieldname should be set as '#all#' because we do not filter an a particular field.
The fieldmovieclips you add minimum one movieclip that should be shown on the map. in this example you add the instance name 'fire_mc'.
When you run the flash application you will see that 20 movieclips have been added to some of the points on the map. Zoom into the map and see it's behavior. The featurelimit property can be set higer but be aware that macromedia flash has a limit in what it can animate at the same time.
The folowing flash application shows you the above example.
